Sorry to bring this back from the dead, but just started looking at spine protectors (actually wanted to find a neck brace, but not sure if the motocross ones will work with snowboard helmets)
I am a 34yr old looking to get into bigger jumps without ending up in a wheelchair

Allsports is having a sale on Demon stuff at the moment so i am looking to get one of the spine protectors through them. Trying to decide between these 3 but appreciate feedback if anyone has it:

DS 1650 Flex Force PRO Top, this is the cheapest, and its a full upper protector. Doesnt seem to go into detail about the back protection abilities though)
